Master Clocks

The GMR1000 and GMR5000are high-precision, multi-function master clocks that can act as an NTP server, PTP grandmaster, time code generator or frequency reference. When equipped with a GPS or GNSS receiver the GMR provides an accuracy ±15 ns to UTC. Base models include both NTP and SNTP client and server functionality compatible with IPv4/IPv6 networks and offer AES256 SSH encryption and MD5 authentication for secure communications. Properly configured and using standard NTP polling rates, our time servers can support and synchronize thousands of simultaneous NTP clients. The GMR can also read NMEA 0183 and NENA messages to set system time, or time can be set manually and the device can generate NMEA, NENA or Truetime/Kinemetrics.
